DIGGING-MACHINE.

SPECIFICATION forming part of vLetters Patent N o. 642,610, dated February 6, 1900. Application filed Oto'iber 5, 1399. Serial No. 732,670. (No model.)

To all whom it may concern,.-

Be it known that I, ALPHENAS V. HYs'oRE, a` resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Digging-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

l My invention relates to an improvement in digging-machines or excavators, one object of the invention being to provide a digger or excavator' which can be pulled along the ground by a draft animal or animals to dig a channel or passage in the ground and at the same time convey the earth dug to one side of the channel or passage.

A further object is to provide a diggingmachine with improved means for regulating the depth of digging.

A further object is to so construct a digging-machine that it can be regulated to deposit the earth on either side of the channel or passage being dug.

With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying'drawings, Figure 1 is a view in side elevation, illustrating my improvements. Fig. 2 is a rear view, and Fig. 3 is a detail view, of the plow.

A represents .a frame, from which depend downwardly-projecting arms l, forming bearings for the rear axle 2. A bracket 3 is secured to the lower face of the frame A and projects forward and is provided -with a screw-threaded opening in alinement with an opening in the frame for the reception of a screw-threaded standard 4, swiveled at its lower end to the front axle 5. A block 6 is secured to the lower face of the frame A and is disposed between the frame and bracket 3 to support said bracket in place. The upper end of the standard 4 is provided with a hand-wheel 7 in proximity to the operators seat 8 to facilitate turning the standard to raise and lower the frame to regulate the depth of digging, as will more fully hereinafter appear.

Wheels 9 and 10, having enlarged and roughened bearing-peripheries, are mounted on the rear axle 2. A sprocket-wheel l1l is secured on the shaft 2 and is connected with another sprocket-wheel 12, secured on a shaft by means of a crossed sprocket-chain 15. The shaft 13 has a drum 16 secured thereon to l receive a belt 17, which latter is passed around Horizontal arms 22 are secured to the lower end of the bracket 19, and a plow 23 is secured to the free ends of said arms. The plow 23 comprises two horizontal parallel bars 24,

' 13, supported in uprights 14 on the frame A, Y.

having a series of alined angular openings to receive a series of angular standards 25, bent forward and downward at their lower ends and sharpened to form teeth 26 to cut and pulverize the ground, to be readily taken up by the buckets 20, The upper bar 24 is provided with a series of set-screws 27 to regulate the position of the standards 25, and it will be seen that the standard 4 can be readily turned by the operator to raise and lower the frame, and hence the bracket 19, carrying the plow and buckets, and thus regulate the depth of digging.

The rear wheel 10 is provided on its inner face with a beveled gear 23, meshing with a gear-wheel 29, secured on a vertical shaft 30. The shaft 30 is swiveled at its lower end in a bracket 3, loosely mounted on the axle 2, and the upper end of said shaft 30 passes through an elongated slot 32' in the frame A and is supported in a movable block 33, loosely mounted on the frame. A gear-Wheel 34 is secured on the upper end of the rshaft 30 above the block 33 and is adapted to mesh with one or the other of two oppositely-disposed gears 35 and 36 on a horizontal shaft 37,- mounted in uprights 38 and 39 on the frame A. A pulley 40 is secured on the rear end of the shaft 37. A cross-bar or strip 41 is secured to the frame A and is provided at each end with a roller 42, around which an endlessapron conveyer 21 is passed, and said apron is disposed in proximity to the drum 16 and IOO is adapted to receive the dirt and earth discharged from the buckets. An endless belt 44 connects the pulley 40 with a pulley on one of the shafts for the rollers 42 to operate the apron 2l to convey the dirt or earth to one side of the machine and discharge the same. A series of idle-rollers 45 are provided for supporting the apron, and a series of idle pulleys 46 are provided for the belt 44.

A lever 47 is fulerumed on the bracket 4 and is disposed in proximity to the operators seat, and a rod 48 connects said lever with the block 33, so that the lever can be operated to move the gear-wheel 34 into mesh with either of the gears 35 or 36, and hence reverse the rotation of the shaft 37 and pulley 40 thereon to reverse the motion of the belt 44 and apron 43 to discharge the dirt and earth on the opposite side of the machine.

A suitable fender 49 is provided near the apron 43 to prevent the dirt or earth from falling off the back of the machine, and the front axle is provided with a suitable tongue 50 for the attachment of draft-animals for drawing the machine along.

My machine is particularlyadapted for use in soft ground, and its operation is as follows: As the machine is pulled along the ground the plow 23 will pulverize the ground and the buckets 20 will take up and convey the earth to and deposit it on the endless apron 2l, which latter will convey the earth and deposit it on the ground to one side or the other of the channel or passage being dug.

Various slight changes might be resorted to in the general form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I would have it understood that I do not wish to limit myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a digging-machine, the combination with a frame, a plow secured thereto and an endless bucket conveyer, of an endless-apron conveyer onto which the bucket conveyer is adapted to discharge, a bevel-gear on one of the rear wheels of the machine, a vertical shaft swiveled at its lower end in a bracket loose on the rear axle, the frame having a longitudinal slot therein for the accommodation ofthe upper end of said vertical shaft, a block on said shaft disposed on the frame, a beveled gear on said vertical shaft-meshing with the gear on the rear wheel, a horizontal shaft earrying a pulley, means for transmitting motion from said pulley to the endless apron, oppositely disposed gears on said horizontal shaft, a gear-wheel on the upper end of the vertical shaft disposed between the oppositelydisposed gears, and means for moving said last-mentioned gear into mesh with one or the other of said oppositely-disposed gears.

2. In a digging-machine, the combination with a frame supported on wheels, of a shaft mounted on said frame, a drum on said shaft, a bracket projecting downward from the frame and carryinga roller, an endless bucket conveyer around said drum and roller, a sprocket-wheel on said shaft and rear axle, a sprocket-chain connecting said sprocketi wheels, an endless apron disposed transversely of the frame and located in proximity to the drinn to receive the earth from the bucket conveyer, means for operating said apron and means for reversing the movement thereof.

3. In a digging-machine, the combination with a frame, of a bracket depending therefrom, arms projecting forwardly from the lower end of said bracket, a horizontal series of teeth connected with the forward ends of said arms and depending below the same,- a transverse conveyer and an elevator extending from the lower end of said bracket to a point above the transverse conveyer.

4. In a digging-machine, the combination with a frame, and a bracket depending therefrom, of arms projecting forwardly from the lower end of said bracket, a transverse head secured to said arms and a series of depending teeth mounted in said head and means for adjusting said teeth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
